The control panel has an external interface necessary to communicate with modules responsible for fire
detection and signalling.
The module power supply for its own circuits and controlled external devices is provided by the main
control panel power adaptor.
See Fig. 9.1 for the module view.
Note 1:
Each potential relay output PK1 ÷ PK7 is protected by a multi-actuation polymer fuse. In the event of a
short circuit, the fuse may isolate the output even after the short circuit is removed (with operating
load).
In order to return the fuse to its normal condition, the output load must be momentarily removed.
Note 2:
The line continuity monitoring system for relay outputs consumes less than 1 mA of current from an
external device, which may cause its slight actuation (unwanted and unfavourable). To avoid such the
situation, the line continuity monitoring circuit should be disabled within the software (no output
monitoring declared) and hardware (output monitoring jumper in 1-2 = ”NO” position).

9.2 OPERATION MODES
9.2.1 Fire extinguishing actuation mode (EXTINGUISHING START)
The actuation condition (EXTINGUISHING START) in the fire extinguishing zone may be established in the
following manner:
1. For the operation in the automatic mode, in the following cases:
a) 2
nd
stage alarm in the fire extinguishing zone with the additional mode:
detection of a fire by at least two detectors operating in the group coincidence or the coincidence
including two fire warning devices installed in a given fire extinguishing zone (variants 13, 14, 15, 16);
b) manual actuation of the proper fire extinguishing zone by pressing the EXTINGUISHING START
push button (together with the PERMISSION push button) on the control panel door;
c) manual actuation (as a result of pressing the EXTINGUISHING START push button) with the
external push button connected to the monitoring line fulfilling the EXTINGUISHING START function.
2. For the operation in the manual mode, in the following cases:
